摘　　要：用联立方程法对单级氨水吸收式热泵的性能进行了模拟研究。联立方程组包括物性方程、各部件传热传质方程以及质量和能量守恒关系式。模拟结果表明,联立方程法具有收敛速度快、灵活性高的特点。还分析了发生温度、冷却温度和精馏温度对系统性能的影响,模拟结果与文献得到的结果相比,吻合很好。Based on a set of nonlinear simultaneous equations, computer simulation program for basic single-effect NH3- H2O absorption heat pump system was developed in the paper. These equations contain equilibrium equations of ammonia-water solutions, heat and mass transfer equations of each component, heat and mass balance equations of the system. The simulation results show that OD simultaneous equations possess fast astringency and high agility etc. characteristics. The effect of genesic temperature, coiling temperature and oufle temperatures on system were investigated, the simulation results show good agreements with the results in the literature .
